Product Info for Daniel Defense DD5 V4 URG 18 inch .308 Winchester Upper Receiver with Flash Hider Assembly

The DD5 V4 URG builds upon the foundation Daniel Defense established in 7.62 AR-style rifles. This highly accurate and durable URG includes an adjustable gas block that allows for a consistent feel whether shooting suppressed or unsuppressed. The perfected bolt carrier group reduces overall recoil impulse and is easy to maintain and operate in all conditions. Designed around a Cold Hammer Forged barrel with an innovative 4-Bolt Connection System, this design dramatically increases the connection surface area between the barrel and upper receiver for increased rigidity/stability to wring out accuracy traditionally only found in high-end bolt action rifles. This DD5 URG is only compatible with DD5 proprietary lowers.image
